I'd purchase the 2022 DCI Finals from DCI, as I always do (have a complete set from 1974 to 2019 AND the 1972, 1973, 1974-1976 sets from Drum Corps World)
However, it looks like the ONLY options for DCI 2022 video on physical media are:
Go to torrent sites, download the video/audio and burn the disc yourself
Record the video/audio from a source (Flo or YouTube) with a software such as OBS, then burn the disc yourself.
There are a few other methods.
People WANT permanent physical media, and there are ways around REDICULOUS obstacles.
